.To all whom 'it may concern Be it known that4 we, DAVID SHANKLAND `and EMERSON. B. HoPKiNsoN, of Nevada Oity, county of levada. StateofOaliforuia, have .invented an Improved Fly-Brush; and we do hereby declare the following description and accompanying drawing are suf- 'cient to enable any person skilled in the art or science to whichl it most nearly appertains to make land use our said inventionor improvements without further invention or experiment,

[Our invention relates to an improved device for keeping a table or'other locality free from tiies, and

-we call it'the shoe-dy machine. V

It consists of an upright shaft, which is provided with twoor more arms ot' ilexible substance or material. A trainof gears driven by la spring causes the vupright shaft 'to/make asemi-revoluton back and forth each way, vibrating thearms -aud waving `the stl-earners, thus dispersiug and preventing the return ofiiies.L l

In order to 'more fully illustrate and explainfour iuvention, reference is had to' the accompanying drawing forming a part of this specication, in-which A represents a stand or boxof any desired size orA pattern.- j

Inside of this box is placed a frame, B.

A shaft, c, extends across this frame and carries a toothed wheel, d.

'A spring, e, is also coiled upon th`is shaft and serves to drive the train, being wound up by a suit-a ble key, which is introduced through a hole in the box A.

A shaft, g, passes across the frame just above the wheel d, and carries a wheel, h, which is provided with largeteeth, asshown.

A shaft, i, above this, carries a,detent,j, which en gages with the large teeth of the wheel h.

Secured to the shaft t' is an arm, k, which is connected with the arm o ou the vertical shaftl by a rod,

n. The shaft l steps in a suitable bearing and rises through the top of the box A.

The rocking of the shaft i, upon which the detent is xed when the spring is wound up', willvcause the arm h to vibrate back and forth, and, throughthe rod n, give to the vertical shaft l a semi-revolution back and forth.

4The upright rod or stai? P is secured in some convenient manner to the upper end ofthe shaftl.

A tube, q,'having two or more short radiating tubes, i

lr, is arranged to slide up and down upon this staff and be xed at any desired point.

Rods or arms, S, from which depend sti-earners, t, made of any pliant or flexible substance or material, have one end inserted in the tubes r, or are otherwise secured to thein, so that when the shaft vibrates the arms will also be vibrated, causing the streamers to wave, thus keeping up a continual motion, which will drive away audvpreventV the approach of dies.

The arms-S can be extended to any desired length, and thus protect a largetable or other place which it is desired to free from illes.

Having thus described our invention,

What we claim, and desire to secure by Letters Patent, isn A {1y-brush, consisting of the train of gears driven by a spring, in combination with the vibrating-arm It', connected with the vertical shaft lby means of the connecting-rod fn, and the vertical shaft P with its radiating-arms s, ,substantially as and for the purpose described. i p l In witness whereof we have hereunto set our hands and seals. l DAVID SHANKLAND.
